Greywater management in Ghana has yet to receive the needed attention even though its current generation and reuse practices pose severe environmental and public health concerns, including odour nuisance, groundwater pollution, and risks from pathogens. This study examined the current greywater generation and reuse patterns among low-income urban residents in Kumasi, Ghana. Data were collected from three communities (Ayeduase, Kotei, and Twumduase) through cluster sampling, and a total of 458 questionnaires were administered to households. The average amount of greywater generated for various activities in low-income urban settlements was 53.7 l/c/d. The results showed that greywater reuse is not common among the study participants, but those who reuse it prefer laundry to kitchen and bathroom greywater. The proportion of greywater reuse was estimated at 20.1%, with 2.6, 0.9, and 17.9% of households reusing greywater from the kitchen, bathroom, and laundry, respectively. Factors that significantly influenced greywater reuse included age, the community of residence, and the type of house. The study suggests that increased education and awareness about greywater treatment, reuse, and impacts in low-income urban communities could lead to increased participation in its management.

加纳的灰水管理尚未得到必要的关注，尽管其当前的发电和再利用做法造成了严重的环境和公共卫生问题，包括气味滋扰、地下水污染和病原体风险。本研究调查了加纳库马西低收入城市居民当前灰水的产生和再利用模式。通过整群抽样从三个社区（Ayeduase、Kotei 和 Twumduase）收集数据，并向家庭发放了总共 458 份问卷。低收入城市住区各种活动产生的灰水平均量为 53.7 升/立方/天。结果显示，灰水再利用在研究参与者中并不常见，但那些再利用灰水的人更喜欢洗衣而不是厨房和浴室灰水。灰水回用比例估计为 20.1%，其中分别有 2.6%、0.9% 和 17.9% 的家庭回用厨房、浴室和洗衣房的灰水。显着影响灰水再利用的因素包括年龄、居住社区和房屋类型。该研究表明，加强对低收入城市社区中灰水处理、再利用和影响的教育和认识可能会导致更多人参与其管理。
